The Province of Prussia () was a province of the Kingdom of Prussia from 1829-1878 created out of the provinces of East Prussia and West Prussia.

To differentiate East Prussia, the territory of the former Duchy of Prussia, from the larger Kingdom of Prussia, "Province of Prussia" was also used as a designation for the region after the crowning of King Frederick I of Prussia in 1701.

Following the First Partition of Poland in 1772, the provinces of East and West Prussia were created in 1773. East Prussia was created out of the former Duchy of Prussia and Ermland, while West Prussia was created out of most of former Royal Prussia.

On April 13, 1824, the Provinces of Prussia and West Prussia were joined in a personal union, and from December 3, 1829, in a real union. On April 1 1878, the united Province of Prussia was divided into the Provinces of West Prussia and East Prussia.
